Syndiotactic poly(propylene- -olefin) copolymers with controlled microstructure and desired properties for oxygen enrichment have been synthesized via metallocene catalysts. The controlled incorporation of comonomers as ...

Biominerals are inorganic-organic hybrid composites formed via self-assembled bottom up processes under mild conditions. Biominerals show interesting physical properties, controlled hierarchical structures and robust ...

Membranes used for the manufacture of condoms eventually can develop tiny pores, thereby decreasing dramatically their effectiveness as a physical barrier against the transmission of infectious agents. A technique was ...

Actualmente la generación de residuos sólidos es uno de los grandes problemas ambientales que afecta significativamente los diferentes ecosistemas del planeta. El componente polimérico en el flujo de residuos urbanos sin ...
